Here are our picks for the best K-Drama series that include infidelity, infidelity, cheating, and love affairs.

First on our list is the 2008 series that made us hate traitors, Temptation of Wife. It’s a typical rags to riches story, in which the (now rich) victim demands revenge on those who brought her down.

Goo Eun-jae (played by Jang Seo-hee) has a husband, Jung Gyo-bin (played by Byun Woo-min), who is having an affair with Shin Ae-ri (played by Kim Seo-hyung). Ae-ri was a sister-like figure to Eun-jae growing up together after being orphaned by an accident.

The husband deserves to suffer and be hated even more, not only because of his infidelity, but because he wanted Eun-jae to come back after she got rich and lived a comfortable life.

6. Two Wives (2009)

This three-part miniseries is short for a Korean drama series, but it’s packed with romance, drama, tears, and pain through its story of forbidden love.

Despite their poor first impressions of each other, the two develop strong feelings when they later meet. The moment she finds out the man she loves is a married man is heartbreaking.

What hits hardest and darkest in Show Window: The Queen’s House is how the main character supports the mistress of the love affair, unaware that she is the victim of that very relationship.
